I spent more than 50 hours since August and got only a few CTD and troubles during my many flights :cool:
Using a laptop (17" GTX980 4Gb so a not really performant and high level one) and joystick (old MS sidewinder I have since fs2000 ou fs98 !!) or new Honeycomb yoke
And I think it is absolutely great for almost "photo scenery" aspect in remote places (therefore not using P3D4 for example anymore despite many orbx or A2A addons and so i collected !) : so much better than before : see enclosed link for some pictures (screenshots from repaints I made) : https://flightsim.to/file/5536/piaggio-p149-sahara-cn-csb :-)
So I would suggest to look for the cause of your "unusual" troubles IMHO
Good luck and happy flights ;-) Jean Marc
